Vehicle Care to use the fluid listed in Recommended Fluids and Lubricants on page 11￿13. 10-15 When to Check and What to Use Manual Transmission Fluid It is not necessary to check the manual transmission fluid level. A transmission fluid leak is the only reason for fluid loss. If a leak occurs, take the vehicle to your dealer and have it repaired as soon as possible. See Recommended Fluids and Lubricants on page 11￿13 for the proper fluid to use. Do not remove the cap to check the fluid level or to top off the fluid level. Remove the cap only when necessary to add the proper fluid until the level reaches the MIN line. Engine Air Cleaner/Filter The brake/hydraulic clutch fluid reservoir cap has this symbol on it. The common hydraulic clutch and brake master cylinder fluid reservoir is filled with either DOT 3 or DOT 4 brake fluid as indicated on the reservoir cap. See Engine Compartment Overview on page 10￿6 for reservoir location. See Engine Compartment Overview on page 10￿6 for the location of the engine air cleaner/filter. When to Inspect the Engine Air Cleaner/Filter Inspect the air cleaner/filter at the scheduled maintenance intervals and replace it at the first oil change after each 80 000 km (50,000 mi) interval. See Maintenance Schedule on page 11￿3 for more information. If you are driving in dusty/dirty conditions, inspect the filter at each engine oil change. Hydraulic Clutch For vehicles with a manual transmission, it is not necessary to regularly check brake/clutch fluid unless there is a leak suspected. Adding fluid will not correct a leak. A fluid loss in this system could indicate a problem. Have the system inspected and repaired. How to Check and Add Fluid Visually check the brake/clutch fluid reservoir to make sure the fluid level is at the MIN (minimum) line on the side of the reservoir. The brake/ hydraulic clutch fluid system should be closed and sealed.
